Sunsama: sovereignty score and 8 European alternatives

Sunsama is a daily planner and task manager that brings tasks from other tools and calendars into one plan for the day. It includes a focus mode, timers and an end-of-day shutdown routine, and connects with calendars and task services such as Google Calendar, Outlook, Asana and Todoist. It is aimed at knowledge workers and professionals who plan their days. Sunsama is available on the web, on macOS, Windows and Linux, and as apps for iOS and Android.

Sunsama is operated by Summay, Inc., which its privacy policy describes as based in the United States. The primary servers are in the US, on Google Cloud Platform, with MongoDB Atlas and AWS, and data from users outside the US is processed there too. Sub-processors include Stripe, Intercom and Cloudflare, and the full list is available on request. The service is proprietary and not open source. For a European organisation, the main considerations are US jurisdiction over a US provider and the absence of any stated European hosting option, so task data containing personal information warrants careful assessment.

Why digital sovereignty matters with Sunsama

Sunsama is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Sunsama hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Sunsama is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Sunsama together with your other vendors and gives a total score, a heatmap and the main risk drivers.
